Dota 2 Update - March 28, 2012

GAMEPLAY- Added Lone Druid!- Fixed small bug in the timing of sequential attacks.- Lifestealer: Fixed being unable to Infest Mud Golems.- Weaver: Fixed Time Lapse interaction with Aegis.- Ancient Apparition: Fixed a bug where Ice Blast could get stuck on the map.- Enabled Lycan in Captain's Mode

UI- The top bar game timer no longer is reset when a game ends.- Heroes in top bar now draw grayscale when dead.- The buyback cooldown time now appears in the gold tooltip.- The buyback cooldown now appears in the form minutes:seconds.

BOTS- Fixed bots being too aggressive about destroying enemy items.- Fixed bug where bots would pick up items like Rapier or Aegis without giving humans a chance at them.- After all humans have picked heroes, the remaining bots will now immediately pick their heroes.- Fixed bug where bots would try to farm the same neutral camp that a human was farming.- Added support for bots buying and placing Observer Wards:. The more of a support a hero is, the more likely they are to buy wards.. If they have a human teammate, they will not purchase enough wards to fully deplete the store.. They will ward the runes, their jungle, and sometimes the enemy jungle (depending on how pushed the lanes are).. They won't go to locations to place wards if they think it's too dangerous.- Fixed bug that would sometimes prevent bots from defending their top/bottom lanes when the tier 3 towers/racks are gone.- Fixed bug where if the incoming threat was small, no one would ever be a selected to defend (typically resulting in no defensive response to creeps).
